How many 3-digit palindromic numbers are there?
To be a 3 digit palindromic number, it must be of the form aba.I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):a can be any of the nine digits 1-9;for each of these b can be any of the ten digits 0-9Thus there are 9 x 10 = 90 three digit palindromic numbers.

What is a palindromic cube?
A palindromic cube is a number that is both a cube of an integer and a palindrome, meaning it reads the same forwards and backwards. For example, ( 1^3 = 1 ) and ( 2^3 = 8 ) are not palindromic, but ( 3^3 = 27 ) is also not palindromic. However, ( 4^3 = 64 ) is likewise not palindromic. An example of a palindromic cube is ( 5^3 = 125 ), as it reads the same in reverse form, although it is important to note that actual palindromic cubes in their entirety are rare.
